- FILTER ATTACHMENT.

Specification of ;Letters Patent.

Patented Oct. 30, 1906.

Application filed July 11. i906. Serial No. 325,705.

The ob'ects of the invention are to improve and simplify theconstruction of such devices; furthermore, to. increase their efiiciencyin operation and to decrease the expense attending their manufacture.

With the foregoing and other objects in View, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the recis'eembodiment of invention herein disclosed can be made within the scope ofthe following claims without departing from the spirit of the inventionor sacrificing any of its advantages.

In the accompanying drawings, forming part of this specification, Figure1 is a side elevation,partly in section, of a filter attachmentconstructed in accordance with the present invention. Fig. 2 is a sideelevation of the inlet-section. Fig. 3 is a similar view of thefilter-section with the filter element detachably secured thereto. Fig.4 is a similar view of the outletsection. Fig. 5 is a transverse sectionon the line 5 5 of Fig. 1. Fig. 6 is a transverse section on the line 66 of Fig. 1. Fig. 7 is a side elevation, partly in section, of amodified form of filter-section and filter element.

Like reference -numerals indicate corresponding parts in the differentfigures of the rawings. f The reference-numeral 1 indicates the in letortion of a main supply-pipe, which I sha hereinafter term the maininlet, and

. the reference-numeral 2 indicates the outlet portion of the'mainsupply-pipe, which I shall hereinafter call the main outlet. These maininlet and outlet pipes may be of any suitable form and proportion, andthey may connect with the roof of the house or with any other suitablesource of water-suply and lead into a cistern or other reservoir inwhich it is desired to collect a supply of strained or filtered water.

The improved filter of the present invention preferably comprises aninlet-section 3, a filter-section 4, a filter'element 5, and anoutlet-section 6.

In order to provide sufiicient space for the filter element 5, so as topermit it to perform its function even when it is partly clogged withsediment or other material, said filter element, together with thefilter-section 4 and the adjoining portions of the inlet-section 3 andthe outlet-section 6, are of considerably larger diameter than the maininlet and outlet sections 1 and 2, as shown in the drawings, and inorder that the main inlet and outlet sections 1 and 2, together with thesections 3, 4, and 5, may be placed flat against the wall of a house orother sup ort the enlarged sections 3, 4, and 5, which preferably arecircular in cross-section, the same as the main inlet 1 and the mainoutlet 2, are eccentrically arranged with respect to said main inlet andoutlet, so that their outer portions will be laterally offset withrespect to the inlet and outlet pipes 1 and 2, Fig. 6. By arranging thesections in the manner described the entire device can be placed flatagainst the wall, as will be apparent.

The inlet-section 3 at its upper end is tapered, as indicated at 7, andis fitted around the lower endof the main inlet 1 said section 3 beingpreferably telesco ed upward upon the main inlet 1 for a istance whichis slightly longer than the filter-section 4, for a purpose hereinafterdescribed. At its lower end the inlet-section 3 is formed with a taperedportion 8, which preferably is produced by crimping the lower end ofsaid section, as shown.

The upper end of the filter-section 4 preferably is slightly expandedor'fiared, as indicated at 9, so as to fit around the lower taperedportion or end 8 of the inlet-section 3. At its lower end thefilter-section 4 preferably is crirnped or otherwise formed with atapered portion 10, which is fitted into the flared or expanded upperend 11 of the out let-section 6. At its lower end the outletsection 6preferably is tapered, as indicated at 12,and is fitted into the upperend of the main outlet 2, as shown.

The preferred means for connecting the sections 3, 4, and 5 with eachother consists of a pair of diametrically opposite radiallyextendingpins 13 13 and 14 14 on the lower tapered ends of the sections 3 and 4,respectively, and a pair of bayonet-slots 15 15 and 16 16 on thesections 4 and 6, respectively. As shown clearly in the drawings, theradial pins 13 of the inlet-section 3 are adapted to fit into thebayonet-slots 15 of the filter-section 4, and the radial pins 14 of thefilter-section 4 are adapted to fit into the bayonet-slots 16 of theoutlet-sections 6, thus constituting simple means for detachablysecuring these different sections together.

While the filter element 5 may be of any suitable form or construction,said element preferably comprises a tapered wire cage, the large end ofwhich is of proper size to fit accurately between the tapered end 10 ofthe filter-section 4 and the flared end 11 of the outlet-section 6, sothat when the sections 4 and 6 are fitted together the filter element 5is securely held in place without the use of any other fastening means,said filter element of course being prevented from slipping downward byreason of the fact that its upper end is of suflicient diameter to restagainst the flared portion 11 of the section 6, and said filter element5 being prevented from becoming upwardly displaced not only by the forceof the water, but also by the tapered end 10 of the section 4, whichpresses it firmly against the section 6, as described. By reason of thissimple construction it will be apparent that whenever the filter becomesworn or clogged with sediment it can be easily and quickly removed forthe purpose of supplying a new filter element or of cleaning the oldone.

In the winter-time, for instance, when it is usually no longer desiredto use the filter element 5, said filter element, together with thesection 4, can be removed entirely from the sections 3 and 6, and saidsection 3 can be slid downward upon the main inlet 1 until its lowertapered end 8 fits into the upper flared end 11 of the outlet-section 6,in which position the radial pins 13 will be engaged with thebayonet-slots 16 to lock the two sections securely together.

When it is desired to simplify the construction of the filter-sectionillustrated in Fig. 3, I prefer to employ the form of device illustratedin Fig. 7, wherein the upper portion 4 of the filter-section isdispensed with, so as to leave only the tapered portion 10. In thismodified form of the invention the filter element 5 instead of beingremovably fitted over the exterior of the tapered portion 10 is fittedinside thereof, as shown, and is soldered or otherwise suitably securedin position. Furthermore, the pins 14 are dispensed with, and thebayonet-slots 15 (shown at the upper end of Fig. 3) are formed in thetapered portion 10, as shown in Fig. 7, whereby when the modified formof filtersection carrying the filter element 5 is placed in the upperend of the outlet-section 6, and the inlet-section 3 is fitted down intothe tapered portion 10 the pins 13 on the portion 8 of the inlet-section3 will extend through the slots 15 in the portion 10 and through theslots 16 in the upper end of the outlet-section 6, so as to lock thefilter element 5 securely in position.

It will be apparent that by the use of the modified construction shownin Fig. 7 the pins 14 on the tapered portion 10 in Fig. 3 can bedispensed with and all the upper por tion 4 of the filter-section can becut away, whereby the arrangement of the device is considerablysimplified.

What is claimed is 1. A filter attachment comprising a filtersectiohhaving a pin and an outlet-section having a bayonet-slot, and a filterelement having one end thereof fitted into the joint between thesections and thereby held in place.

2. A filter attachment comprising a section having a tapered portionprovided with a pin, a section having a flared portion formed with abayonet-slot, and a filter element having its large end fitted betweenthe flared and tapered portions of said sections and formed with abayonet-slot.
